Like their sweet counterparts, savory palmiers are an incredibly easy secret weapon to have in your kitchen arsenal. There are always times where people are coming over, and you would like to have a little nibbley something to offer, but are out of time, energy, and ideas. These pesto palmiers are the perfect solution. Frozen puff pastry, pesto (either homemade or from the store), and Parmesan cheese (all of which I always have on hand) are all that you need. Take your thawed puff pastry sheet, and on a floured surface, roll it out to roughly thirteen inches squared. Spread about a third of a cup of good quality pesto over the entire surface, and sprinkle with Parmesan cheese. Fold each side three times, meeting in the middle, and then fold it over onto itself. Slice the log into half inch slices, and place them cut side down on a baking sheet, brush with a beaten egg, and bake at 400º for fifteen minutes, or until nicely golden brown. They are buttery, and flaky, with a delightfully savory kick. The perfect little thing to serve with cocktails. Enjoy!
